To all whom it may concern."

Be it known that we, LEROY W. BROWN and ALFRED BIRNIE, citizens of theUnited States of America, residing at Springfield, in the county ofHainpden and State of Massachusetts, have invented new and usefulimprovements in. Machines for Scoring Paper- Board, of which thefollowing is a specification.

This invention relates to improvements in mechanisms for scoring sheetsof paper or cardboard of such general class as is exemplified by themechanism described in Letters Patent oi the United States to ChaunceyVS. Gray, October 23, 1894:, No. 527,903.

The present improvement relates to the means for causing the wastestripr shaving which is excavated from the cardboard by the plow or blade tobe constrained to move tangentially or substantially so outwardly fromthe scoring-wheel so that it may not be carried around within the grooveof the wheel to clog or interfere with the scoring action of the wheel;and to this end the invention consists in the combination with thedoublecdged scoring-wheel of a band of suitable material arranged withinthe groove of, and loosely surrounding, the wheel, and having a part orprojection which extends beyond the cutting edges of the wheel and whichis adapted to abut against some fixed part or to be supported orrestrained thereby from unduly rotating with the wheel, and which servesas a deflector to guide out the waste strip or shaving.

In the accompanying drawings, Figure 1 shows in side elevation andpartial section a part of a scoring-machine with a sheet of paper-boardbeing fed therethrough and showing the improved guide for leading outthe waste strip. Fig. 2 is a sectional view through the double-edgedscoring-wheel centrally and transversely of its axis, and showing theencircling waste-guide. Fig. 3 is an edge view of the scoring-wheel andthe encircling wasteguide, a front portion of the latter being shownasbroken ed and in section. Fig. 4: is a view of a slightly-modifiedconstruction to be hereinafter referred to.

In the drawings, A represents the holder for the scoring-wheel ll, saidholderhaving thereon the bifurcated shoe J constructed with the apertureor throat 9 through. the shank g. j represents the excavator or plowmounted. on

and projected inwardly beyond the heel of the I shoe. These parts areall substantially as seen in the aforesaid p2 tent.

T he leading-out guide for the waste strip consists of a band M, ofsuitable materialsuch, for instance, as wire looped around into a circleand having its ends brought together and extending radially from thecircle described by the major part of the said band. As specificallyshown the ends of the wire are brought together and twisted, as seen atm, Figs. 1, 2, and 3. The said band M is of such diameter that it maythe wheel, loosely, and have more or less deflection therein in theplaneof rotation thereof, so that the cuttingedges of the wheel at theirlowermost part will protrude below the thickness of the band, whenoperating onthc work, as seen in Fig. l. The friction, oftentimes, atthe inner sides of the sharp flan "of the scoring-wheel H, upon theopposite sides of the band, will cause the said band to be swung around,as the wheel rotates, so that its nose or radial projection m abutsagainst the portion of the shank g of the shoe at the upper boundary ofthe clearing-throat g and forms a barrier against the passage of the-waste strip or shaving around in the groove of the scoring-wheel.

When the machine is not running, the leading-out band M may drop down sothat the nose m thereof will drop, against the base of the throat g butthis is merely incidental and if desired the band may have itsmosescoured to the part of the shoe at the upper boundary of the throat, andsuch a connection of the parts is indicated in Fig. 4, and in thisfigure the wire may be a flat wire like a Watch-spring or it may be ofother material or form and, again, the invention is not liinited to thecombination of the leading-out band substantially as described with anyparticular part which restrains it or supported t. against undulyrotating, for its combination with the scoring-wheel, substantially asdc scribed, may be made available in many dc lie within the groove inscriptions of scoring mechanisms wherein such a double edged andintermediatelygrooved Wheel is employed.

Having thus described our invention, what we claim, and desire to secureby Letters Petcut, is

In a, scoring mechanism, the combination with a double-edged scoringWheel having the intermediate peripheral groove, of a band 10 looselyencircling the wheel Within the groove 0 I I u and having an outwardlyprog ecting part, and a a, stationary part with which the outwardlyprojecting part of the encircling hand en gages, substantially asdescribed.
